Introduction to Kalimantan silica sources

High quality silica or quartz sand mined in Kalimantan (on the island of Borneo, Indonesia) is famous for its high SiO₂ purity (>98–99.7%) and very low iron (Fe₂O₃) content (~0.006–0.12%)

Suppliers such as PT. Borneo Silika Pasifik and its partners in Central and East Kalimantan have developed silica mines with modern mining technology, supplying regularly to the Southeast Asian and international markets

Products provided by Unite Vietnam

Outstanding features:

• High purity: SiO₂ ≥99%, moisture ≤6%, impurity content such as Fe₂O₃ is only about 120 ppm - suitable for glass production, casting, paint, solar panels...
• Standard particle size: customized mesh size (eg: 10–150 mesh) to suit industrial production processes

Supply chain advantages:

• Direct import source from Kalimantan: ensure stability, transparency of product origin
• Smooth import process: support CO/CQ certification, implemented at Vietnamese ports and complete delivery according to customer requirements.

Typical applications

• Production of high tech glass and glass: pure silica SiO₂ helps avoid bubbling, increases transparency.
• Mold casting in mechanical industry: use uniform-sized silica, low impurities to improve mold surface accuracy and quality.
• High-grade industrial materials: used in solar cells, paints, coatings - where impurity-free silica sand is required.
• Industrial water treatment: create a stable filter layer, effectively absorb iron and heavy metals.

With the supply of industrial grade Kalimantan silica (Indonesia), high purity and low impurities, and a professional logistics chain, Unite Vietnam is a reliable partner for enterprises producing technical glass, casting, clean energy batteries, and processing technical materials.
